I am a seasoned Senior Software Engineer with a passion for building scalable systems and delivering exceptional user experiences. With over six years of expertise spanning backend, frontend, and cloud technologies, I thrive on solving complex challenges in high-performance environments. On the backend, I specialize in Java, Kotlin, Spring Boot, and Node.js, crafting microservices and distributed architectures designed for reliability and efficiency. My experience includes developing mission-critical features for platforms like Expedia and Hotels.com at EPAM Systems and optimizing a high-load chat system for OLX that handled over 1 million requests per minute. I am well-versed in tools like Kafka, Redis, and Cassandra, ensuring robust and fault-tolerant solutions. Cloud computing and DevOps are at the core of my work. Proficient in AWS (EKS, Lambda, DynamoDB, S3) and GCP, I’ve executed complex cloud migrations, optimised CI/CD pipelines, and automated deployments using Kubernetes, GitLab, and Helm. My ability to ensure zero downtime during migrations and optimise costs demonstrates my commitment to delivering operational excellence. At OLX, I successfully migrated a Cassandra cluster containing over 1 billion records to a new AWS account with zero downtime. This project demanded meticulous planning and execution, showcasing my ability to deliver mission-critical cloud solutions My frontend experience complements my backend expertise, with proficiency in ReactJS, Redux, Material UI, and Zustand. I create user-focused interfaces that are both responsive and engaging. At Vyapar Apps, I migrated critical Android app modules to Kotlin using MVVM architecture, boosting maintainability and performance. I have experience working across the entire software development lifecycle, from requirement gathering and architecture design to implementation, testing, and deployment. My collaborative approach ensures that I deliver solutions that not only meet technical requirements but also align with business objectives. Beyond development, I contribute as a technical leader, mentoring teams, advocating best practices, and fostering innovation. I take pride in writing clean, efficient code and implementing design patterns that ensure long-term scalability. Whether it's backend optimisation, cloud architecture, or frontend development, I am driven by the challenge of creating impactful solutions that meet both technical and business goals. Let’s connect and explore opportunities to build the next generation of scalable, user-centric applications.
